Details

Zipp’s 303 SW Carbon Tubeless Disc Brake Rear Wheel delivers efficient speed, improved control, and greater comfort across a range of surfaces. Designed for modern riding, it features a 40mm deep carbon rim, wide internal profile, and integrated AXS tyre pressure sensor for real-time monitoring. The refined construction offers improved impact strength and smooth performance, whether you're on the road, gravel, or mixed terrain.

Key Features and Benefits:

  • Integrated Zipp AXS Wheel Sensor: Allows on-bike tyre pressure monitoring in real time without valve-mounted devices. Helps riders fine-tune pressure pre-ride and during rides. This ensures better grip, lower rolling resistance, and reduced risk of damage.
  • Wide 25mm Internal Rim Width: Supports wider tyres for use at lower pressures. This increases comfort and stability across mixed surfaces. The outcome is reduced rider fatigue and better control on rough terrain.
  • 40mm Carbon Rim Depth with Aero Profile: Reduces aerodynamic drag by improving the airflow transition between the rim and wider tyres. Delivers greater speed with less effort, especially on open road sections.
  • Hookless Carbon Construction: Provides a consistent interface with tubeless tyres. This results in better sealing, safer performance at lower pressures, and reduced pinch flats.
  • Improved Carbon Layup and Structure: Increases impact strength by nearly 10% over the previous version. Enhances durability while keeping weight low, supporting aggressive riding in demanding conditions.
  • Optimised for 30–35mm Tyres: Offers best performance with 35mm setups. Balances speed, grip, and comfort for all-road versatility.
  • ZR1 Hub with Stainless Steel Bearings: Provides smoother rolling and greater longevity. Ensures low maintenance performance over time and across terrain types.
  • Reduced Tyre Deflection and Rolling Resistance: Wide stance minimises deformation under load. This helps maintain momentum and improves efficiency over long distances.

Designed for riders who prioritise efficiency over all surfaces, the Zipp 303 SW rear wheel offers a balance of speed, grip, and durability. The integration of tyre pressure monitoring is especially useful for those who want full control of their setup on varied terrain. Its wide, hookless carbon rim supports tubeless performance at lower pressures, translating to less fatigue and more comfort over time. With a revised build for added strength and smooth ZR1 hubs, it stands up to real-world riding with minimal compromise.

Ride smarter and smoother with a wheel built to perform across all-road challenges. Engineered for speed, strength, and control—it's ready for your fastest miles yet.
